CAUTION! 1. FSB1333-CPU will operate in overclocking mode. Under this situation, PCIE frequency will also be overclocked to 115MHz. Besides, if you want to overclock the CPU you adopt from FSB800 to FSB1066, you need to adjust the jumpers. Please refer to page 18 for proper jumper settings. 2. About the setting of "Hyper Threading Technology", please check page 30. 3. This motherboard supports Untied Overclocking Technology. Please read "Untied Overclocking Technology" on page 24 for details. 4. This motherboard supports Dual Channel Memory Technology. Before you implement Dual Channel Memory Technology, make sure to read the installation guide of memory modules on page 16 for proper installation. 5. Please check the table below for the CPU FSB frequency and its corre- sponding memory support frequency. CPU FSB Frequency Memory Support Frequency 1333 DDR2 533*, DDR2 667 1066 DDR2 533, DDR2 667 800 DDR2 400, DDR2 533, DDR2 667 533 DDR2 400, DDR2 533 * When you use a FSB1333-CPU on this motherboard, it will run at DDR2 500 if you adopt a DDR2 533 memory module. 6. Due to the chipset limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® XP, Windows® XP 64-bit, Windows® VistaTM and Windows® VistaTM 64-bit. 7. The maximum shared memory size is defined by the chipset vendor and is subject to change. Please check Intel® website for the latest information. 8. Before installing SATAII hard disk to SATAII connector, please read the "SATAII Hard Disk Setup Guide" on page 23 to adjust your SATAII hard disk drive to SATAII mode. You can also connect SATA hard disk to SATAII connector directly. 9. Power Management for USB 2.0 works fine under Microsoft® Windows® VistaTM 64-bit / VistaTM / XP 64-bit / XP SP1 or SP2 / 2000 SP4. 10. Featuring an advanced proprietary hardware and software design, Intelligent Energy Saver is a revolutionary technology that delivers unparalleled power savings. In other words, it is able to provide exceptional power saving and improve power efficiency without sacrificing computing performance. Please visit our website for the operation procedures of Intelligent Energy Saver. ASRock website: http://www.asrock.com 11. Although this motherboard offers stepless control, it is not recommended to perform over-clocking. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU. 8
